[0002] A sealed pulse controller is a device specifically designed to control pulse signal output and is widely used in the field of automation control. This type of controller can precisely control the frequency, width, and interval of pulses, making it suitable for applications requiring precise pulse control, such as the dust removal control of pulse jet bag filters. However, current pulse controllers lack dust protection, which shortens their lifespan and operating time, and also affects their working efficiency.

[0003] According to the description in the patent announcement (CN215232942U) of a sealed pulse controller with a dustproof structure, the sealed pulse controller with a dustproof structure includes "device, cover, rotating column" etc., to perform dustproof work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This sealed pulse controller with a dustproof structure uses a device, cover, rotating column, etc. to prevent dust. During use, the dustproofing of the front of the controller is achieved by rotating the cover. However, the dustproofing range is small and incomplete, allowing dust to still enter the controller during use. Furthermore, the dustproofing and protection effects are poor, so this controller needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a sealed pulse controller with a dustproof structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sealed pulse controller with a dustproof structure, including a mounting frame, a dustproof mechanism on the front side of the mounting frame, and a limit mechanism on the top of the dustproof mechanism;

[0008] The dustproof mechanism includes a fixed base, which is fixedly connected to the front side of the mounting frame. A protective shell is slidably connected inside the fixed base. A bidirectional threaded rod is rotatably connected inside the fixed base. A knob is fixedly connected to the right side of the bidirectional threaded rod. A movable frame is threadedly connected to the periphery of the bidirectional threaded rod. A slide rod is slidably connected inside the movable frame. A fixed frame is fixedly connected to the front side of the movable frame. A controller body is disposed inside the fixed frame. A fixed rod is fixedly connected to the right side of the fixed frame. A connecting plate is slidably connected to the periphery of the fixed rod. A connecting rod is fixedly connected to the right side of the connecting plate. A buffer plate is fixedly connected to the right side of the connecting rod. A first spring is sleeved around the periphery of the fixed rod.

[0009] Preferably, the fixed base has a limiting groove inside, the protective shell is slidably connected to the limiting groove, and the protective shell has a wiring groove inside, which is rectangular in shape, so that the protective shell can be in a preliminary stable state under the action of the limiting groove.

[0010] Preferably, the bottom of the fixing frame is in contact with the bottom of the controller body, and a rubber pad is provided on the inner side of the fixing frame to facilitate the fixing of the controller body under the action of the fixing frame.

[0011] Preferably, the left side of the first spring is fixedly connected to the right side of the fixed frame, and the right side of the first spring is fixedly connected to the left side of the connecting plate, so that the buffer plate can be buffered under the action of the first spring.

[0012] Preferably, the limiting mechanism includes a support frame, which is fixedly connected to the rear side of the fixed seat. A limiting rod is slidably connected inside the support frame. The bottom of the limiting rod is inserted into the protective shell. A limiting ring is fixedly connected to the top of the limiting rod. A second spring is sleeved around the limiting rod.

[0013] Preferably, the limiting rod passes through the inside of the fixed base, and the fixed base and the protective shell are respectively provided with slots, and the two slots correspond to each other. The limiting rod is inserted into the slot, so that the protective shell can be limited under the action of the limiting rod.

[0014] Preferably, the top of the second spring is fixedly connected to the bottom of the limiting ring, and the bottom of the second spring is fixedly connected to the top of the support frame, so that the limiting rod can be kept in a stable state under the action of the second spring.

[0015] Compared with the prior art, this utility model provides a sealed pulse controller with a dustproof structure, which has the following advantages:

[0016] This sealed pulse controller with a dustproof structure utilizes a dustproof mechanism. When the controller is in use, the mounting bracket is fixed near the equipment or inside the control cabinet where it is used, ensuring stability of the mounting bracket and the fixed base. Simultaneously, the spacing between the fixed frames can be adjusted according to the size of the controller by means of a bidirectional threaded rod, sliding rod, and movable frame, thus securing the controller and ensuring its stability. Furthermore, the protective shell is slidably connected inside the fixed base, providing dustproof protection for the controller. This dustproof measure reduces the entry of dust and other fine particles into the controller, ensuring its stability and reliability. Moreover, when the controller is in dustproof mode and collides with the protective shell due to external factors, the buffer plate, connecting rod, connecting plate, and first spring cushion the impact, further ensuring the stability and safety of the controller.

[0017] This sealed pulse controller with a dustproof structure, through a set limiting mechanism, can achieve the following: when the controller body is fixed and in operation, the protective shell is slidably connected to the fixed base to protect the controller body from dust. Under the action of the limiting rod, the second spring and the limiting ring, the protective shell can be limited, keeping it in a stable state and facilitating the installation and removal of the protective shell, thereby improving the efficiency of maintenance, repair and operation of the controller body.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides the following technical solution:

[0030] Example 1, please refer to Figure 1-7 This utility model provides a technical solution: a sealed pulse controller with a dustproof structure, including a mounting frame 1, a dustproof mechanism 2 is provided on the front side of the mounting frame 1, and a limit mechanism 3 is provided on the top of the dustproof mechanism 2;

[0031] The dustproof mechanism 2 includes a fixed base 21, which is fixedly connected to the front of the mounting frame 1. A protective shell 23 is slidably connected inside the fixed base 21. A bidirectional threaded rod 25 is rotatably connected inside the fixed base 21. A knob 22 is fixedly connected to the right side of the bidirectional threaded rod 25. A movable frame 26 is threadedly connected to the outside of the bidirectional threaded rod 25. A slide rod 28 is slidably connected inside the movable frame 26. A fixed frame 27 is fixedly connected to the front of the movable frame 26. A controller body 24 is provided inside the fixed frame 27. A fixed rod 292 is fixedly connected to the right side of the fixed frame 27. A connecting plate 293 is slidably connected to the outside of the fixed rod 292. A connecting rod 294 is fixedly connected to the right side of the connecting plate 293. A buffer plate 29 is fixedly connected to the right side of the connecting rod 294. A first spring 291 is sleeved around the outside of the fixed rod 292.

[0032] The fixed base 21 has a limiting groove inside, and the protective shell 23 is slidably connected to the limiting groove. The protective shell 23 has a wiring groove inside, and the wiring groove is rectangular, so that the protective shell 23 can be initially stabilized under the action of the limiting groove. The bottom of the fixed frame 27 is in contact with the bottom of the controller body 24. The inner side of the fixed frame 27 is provided with a rubber pad, so that the controller body 24 can be fixed under the action of the fixed frame 27. The left side of the first spring 291 is fixedly connected to the right side of the fixed frame 27, and the right side of the first spring 291 is fixedly connected to the left side of the connecting plate 293, so that the buffer plate 29 can be buffered under the action of the first spring 291.

[0033] Example 2, please refer to Figure 1-7 Furthermore, based on Embodiment 1, the limiting mechanism 3 further includes a support frame 31, which is fixedly connected to the rear side of the fixed base 21. A limiting rod 32 is slidably connected inside the support frame 31. The bottom of the limiting rod 32 is inserted into the interior of the protective shell 23, and a limiting ring 34 is fixedly connected to the top of the limiting rod 32. A second spring 33 is sleeved around the limiting rod 32. The limiting rod 32 passes through the interior of the fixed base 21. Slots are respectively opened inside the fixed base 21 and the protective shell 23, and the two slots correspond to each other. The limiting rod 32 is inserted into the slot, so that the protective shell 23 can be limited under the action of the limiting rod 32. The top of the second spring 33 is fixedly connected to the bottom of the limiting ring 34, and the bottom of the second spring 33 is fixedly connected to the top of the support frame 31, so that the limiting rod 32 can be kept in a stable state under the action of the second spring 33.

[0034] In actual operation, when this device is used, firstly, the mounting bracket 1 is fixed near the equipment where the controller body 24 needs to be used or inside the control cabinet using external fixing equipment, so that the mounting bracket 1 and the fixing base 21 are in a stable state. According to the size of the controller body 24, the controller body 24 is positioned inside the fixing frame 27. Rotating the knob 22 causes the bidirectional threaded rod 25 to drive the movable frame 26 to move, and the movable frame 26 slides around the slide rod 28. Under the action of the movable frame 26, the distance between the fixing frames 27 can be adjusted, so that the fixing frames 27 move to the left and right sides of the controller body 24, and the bottom of the fixing frame 27 is aligned with the control body 24. When the bottoms of the controller body 24 come into contact with each other, the controller body 24 is in a stable state. At the same time, pulling the limit ring 34 upward will move the limit rod 32 and the second spring 33, which will slide the protective shell 23 into the fixed base 21. Releasing the limit ring 34 will reset the second spring 33, allowing the limit rod 32 to be inserted into the slot inside the fixed base 21 and the protective shell 23, thus stabilizing the protective shell 23 and protecting the controller body 24 from dust. When it is necessary to connect an external connection cable to the controller body 24, the connection can be made simply through the wiring groove inside the protective shell 23, making the operation convenient.

[0035] When the protective shell 23 is impacted by external factors, the protective shell 23 will compress the buffer plate 29, causing the connecting rod 294 to drive the connecting plate 293 to slide around the fixed rod 292, and compress the first spring 291. Under the elastic action of the first spring 291, the buffer plate 29 can be buffered, ensuring the stability and safety of the controller body 24. The controller body 24 used in this case is model QYM-FC-ED.
